In which patient group is Vesicoureteral reflux more likely to be suspected when a UTI is present?

• A. Child or neonate
• B. Elderly patient with nocturia
• C. Pregnant woman with no symptoms
• D. Elderly woman with prostatic hypertrophy

Answer: (A)

Vesicoureteral reflux is most often considered in children, including neonates, when a urinary tract infection occurs. In kids, a UTI raises the suspicion for reflux because a congenital weakness at the vesicoureteral junction can allow urine to flow backward from the bladder toward the kidneys, increasing the risk of pyelonephritis and potential renal scarring. This pediatric connection is why clinicians frequently evaluate young patients with UTIs for VUR, using imaging such as a voiding cystourethrogram in appropriate cases. In adults, UTIs are typically due to factors like bladder dysfunction, obstruction, stones, or other pathogens, and reflux is not usually the primary concern. Pregnant women with UTIs are evaluated for bacteriuria and treated, but VUR is not a common focus unless there are atypical findings. Elderly individuals with prostatic hypertrophy develop UTIs mainly from incomplete emptying and stasis, not reflux. Therefore, the patient group in which VUR is most likely to be suspected when a UTI is present is children or neonates.
